FiveM Script Development and Server Setup
We write custom scripts for your FiveM server, adapt existing ones, and set up and run the server itself. We work on QBCore, Qbox and ESX and build community-specific systems from scratch, from inventories and MDTs to phones and anti-cheat. Since 2019 we have worked on more than 800 game servers, most of them FiveM roleplay servers.
What this service covers.
These items are planned together or separately depending on the project. We clarify which ones you need during the discovery call.
- Custom scripts from scratch for QBCore, Qbox and ESX
- Adapting bought or existing scripts to your server, framework conversions
- NUI interfaces in React or Vue: HUDs, phones, MDTs, inventories, menus
- Server setup: txAdmin, OneSync, database and resource layout
- Performance tuning: resmon, network events and database queries
- Server-side validation, cheat and exploit prevention, logging
- Discord integrations, whitelisting, Tebex store hookups
- Maintenance, updates and bug fixing for live servers
What we build for FiveM
What sets a roleplay server apart is the systems players touch every day. Job and economy scripts, MDTs for police and EMS, phones, inventories, vehicle and housing systems, money laundering and gang mechanics, admin tools: we write all of them to fit your community's rules.
On the interface side we work with NUI. We design and build HUDs, phones, tablets and menus in React or Vue so they run smoothly in game. Game logic is written in Lua, and in C# or JavaScript where it fits; we stay compatible with common libraries such as ox_lib, oxmysql and ox_inventory.
QBCore, Qbox or ESX?
If you already run a server, we work on its framework, and we can also move scripts from ESX to QBCore or from QBCore to Qbox. If you are starting out, we choose together based on your expected player count, the scripts you want to use and your team's experience.
Our FiveM server setup guide covers the framework decision in detail. If you would rather start from a ready, installed server than build from scratch, our turnkey package F Core, with a core compatible with QBCore and Qbox scripts, is made for that.
Performance and security
As player counts grow, what slows a server down is rarely one script. It is small problems piling up: loops running every frame, needless network events, unindexed database queries. We measure the bottlenecks with resmon and the profiler, fix the code and show the result in numbers.
On security the rule is simple: never trust data coming from the client. We validate money, item and permission actions on the server, close exploitable events, and log every important action so you can resolve reports. We also set up proxies and DDoS protection to keep your server online under attack.
How we work
We start by listening to what you need and agreeing on scope and budget. Development happens on a test server and you try interim builds with your team; going live happens at a low-traffic hour with a rollback plan.
We stay with you after delivery: we keep scripts compatible with FiveM and framework updates, fix bugs and add new systems. You receive the source code, so your server never depends on us.
Frequently asked questions, answered briefly.
It depends on scope. A single job script or interface takes a few days; larger systems such as an MDT or phone take a few weeks. Once we have your request we give you a clear timeline and quote.
QBCore, Qbox and ESX. We also write standalone scripts, and we build to be compatible with libraries such as ox_lib, oxmysql and ox_inventory.
Yes. We adapt open-source scripts to your framework and your other systems and resolve conflicts. For escrow-protected scripts, only the configuration files the author left open can be changed.
Yes. We measure which resources cause load with resmon and the profiler, then fix loops, network events and database queries. We share before and after measurements with you.
We hand over the source code of scripts built for you. You can use them on your server as you like and keep developing them with your own team.
Yes. F Core is our turnkey FiveM roleplay server package, delivered installed with its systems ready. See the F Core page for details.
